Gary Cox (Glazing) Ltd have been using Sigma for in excess of 25 years. Sigma deliver an excellent product. Pam and Dee are always on hand to offer their expertise and advice on their products. They couldn’t be more helpful. – Mary Cox

I have had dealings with Sigma for the last 28 years. Kevin Cross the founder of Sigma evolved the company after working at Smarts as there factory manager. For this reason alone Sigma always had an edge on other fabricators as all Sigma staff were “Smart” people. Over the years I have installed other companies products but there is always something not quite right. The thing Sigma brings to the table is high quality, very well made Aluminium products at very competitive prices. It still to this day is family run, as well as “Smart” people business. Of course now and again you will get the odd problem but Sigma will bust a gut to put it right as quick as possible. If anyone ever asks me where I buy my Aluminium there’s only every one answer Sigma. My advise to any window companies out there looking for an Aluminium fabricator is to look no further call Sigma tomorrow. Its the only Aluminium company I will put my name to. – Paul Tripp Installations Ltd
